That is definitely going to be the challenge and a point of concern utilizing essentially 2 different subwoofers. I am wondering how well dual sub control with Audyssey 32 will work in this setup.

I am sure I will spend a lot of time working this issue out, but I think it's doable and IMAX will have nothing on me...well except for a much larger screen, more power and a ton more speakers...but hey it will be good
